Why does an apollo hoeticulture 600 watt hps/mh ballast with cool tube only fire up the metal halide bulb. it is new and came with 1 bulb each.I figured the hps bulb was bad because it didnt fire but the metal halide did. Today i received a new badass bulb hps 600. it wont fire up either? Am I doing something wrong or is it a technical issue.
what can I do?
